Gaby, can we have this patch in 4_1-branch too?

Also, about the POD issue (now tracked as libstdc++/25626) I think is
sufficiently serious from the conformance point of view to warrant a
rather urgent action: do you want me to extract a minimal fix from your
large draft of a few weeks ago? I think I understand the problem
sufficiently well.
